Description
Atlas Bejca Sealer 06 Teak is a semi-transparent, silicone-resin staining impregnant that finishes the Atlas concrete and wood-effect render range, turning Cermit WN render into an authentic teak timber-board facade. A 4-litre tin covers 26–40 m² per coat at 0.10–0.15 kg/m², dries in around 30 minutes, and resists rain after roughly 24 hours, so a typical elevation can be sealed and colour-finished within one working day.
Where Atlas Bejca Teak Performs Best on UK Facades
Atlas Bejca 06 Teak is the colour-and-protection layer for Atlas Cermit WN wood-stamped render, formulated with polymer dispersions and silicone resins that lock a mid-tone teak grain into cured mineral render at 0.10–0.15 kg/m² per coat, with hydrophobic protection that holds for 5–12 years on UK elevations. The depth of warmth you get on a south-facing facade depends almost entirely on the first coat — keep that one thin and the grain reads cleaner under low autumn sun.
The product earns its place on three project types: full external wood-effect facades over ATLAS ETICS or ROKER EWI build-ups, feature panels on porches and plinths where a timber aesthetic is wanted without timber maintenance, and interior accent walls in commercial and residential reception areas. It bonds to cured Cermit WN, standard concrete, smooth and textured mineral renders, gypsum render and putty, and plasterboard, which is what makes the same tin usable inside and out.
Why Trade Specifiers Choose Atlas Bejca Teak
- Authentic teak grain depth: Semi-transparent UV-stable pigments build a warm mid-tone wood read on stamped render, giving facades the look of timber boards with none of the recoating cycle real timber demands.
- Hydrophobic silicone film: Rain beads off the cured coating rather than soaking in, which keeps dust and atmospheric soiling from settling into the stamped grooves and preserves the original colour for years.
- Same-day facade turnaround: Around 30 minutes drying between coats lets a two-coat finish go on inside a single shift, with early rain resistance after roughly 24 hours — useful for tight UK weather windows.
- Flexible polymer binder: The cured film moves with normal thermal expansion of the render panel, so the colour layer stays intact rather than crazing along stamp lines as temperatures swing.
- Cross-substrate compatibility: One product covers Cermit WN, concrete, mineral renders, gypsum render, and plasterboard, which simplifies ordering on mixed exterior–interior projects.
- Specified system component: Sits within ATLAS ETICS and ROKER BBA-certified EWI build-ups, so the wood-effect aesthetic does not break the certified render finish path.

How to Apply Atlas Bejca Teak — Coats, Coverage, Conditions
Application starts on cured Cermit WN that has hardened for a minimum of 3 days at +20 °C and 50% relative humidity. Stir the tin gently before use and at intervals during the job so the semi-transparent pigments stay evenly suspended — settling produces darker bands at the bottom of a panel that are hard to disguise.
- Coat 1 — thin: Brush at the lower end of the range (around 0.10 kg/m²), working product into the stamp grooves first, then smoothing flat areas with a medium-nap roller. A thin first pass lets the grain read clearly under direct light.
- Coat 2 — standard: After roughly 30 minutes, apply a second coat at 0.12–0.15 kg/m² to deepen the teak warmth and complete the hydrophobic barrier. Two coats is the practical maximum on most facades.
- Weather window: Stay between +5 °C and +25 °C with no rain forecast for 24 hours after the final coat — the polymer–silicone film needs that cure time to reach full water repellence.
- Tool choice: Soft-bristle brush for the grooves, medium-nap roller for the flats. Spraying is not recommended on stamped texture because the grooves do not receive even saturation.

Installation Notes — Drying, Finish Depth, Site Conditions
Two coats deliver the canonical teak look; one coat gives a lighter, sun-bleached read that some specifiers prefer on heritage-style elevations. Work groove-first, then flat-areas, rather than rolling the whole surface and trying to push product into the recesses afterward — the groove-first sequence puts the deepest pigment exactly where the eye expects to see grain depth.
Allow the full 24-hour rain-resistance window before evening dew falls if you finish late in the day, and keep a covered tarp set up for elevation transitions where weather can turn quickly. On large facades, work in panel-sized sections that you can complete in a single coat without joins breaking across the wet edge.
Pro Tips From UK Installers Using Atlas Bejca Teak
- Sample board first: Stamp a 600 × 400 mm panel of Cermit WN, cure it for 3 days, then trial your two-coat sequence. The cured-render colour and stamp depth both affect how teak reads on the actual facade.
- Thin first coat wins: I always pull the first coat back to roughly 0.10 kg/m². Teak builds warmth fast on coat two, and a heavy first pass pools in the grooves and creates dark patches that resist evening-out.
- Stir every 15 minutes: Pigment settles during longer breaks. A quick re-stir keeps the bottom-of-tin product the same shade as the top-of-tin.
- Watch wet-edge timing: 30-minute recoat means panels can flash dry in summer. Plan section sizes so the wet edge stays live until you reach a stamp line or external corner.
- Order one extra tin: Coverage varies with stamp depth and render porosity. A spare 4-litre tin avoids stopping mid-facade if absorption runs higher than the 0.15 kg/m² figure.
Is Atlas Bejca Teak Right for Your Project?
- Right for warm mid-tone wood facades: A natural teak board read on full elevations, plinths, porches, or interior feature walls within ATLAS ETICS / ROKER systems.
- Deeper brown alternative: The Atlas Bejca Walnut 4L delivers a darker, richer wood tone for more dramatic facades, using the same two-coat method.
- Lighter Scandi alternative: The Atlas Bejca Birch 4L produces a pale, Scandinavian timber look — useful for north-facing elevations where dark tones absorb less light than you want.
- Smooth concrete look instead: If the design moves away from wood, Atlas Cermit WN smooth render can be finished without stamp or sealer for a clean concrete-effect facade.
FAQ — Atlas Bejca Teak Coverage, Compatibility, Ordering
How much Atlas Bejca Teak do I need for my project?
Each 4-litre tin covers 26–40 m² per coat depending on render porosity and stamp depth. For a standard two-coat finish on moderately absorbent Cermit WN, plan for roughly 13–20 m² of completed facade per tin. Measuring elevations in advance and adding one spare tin for projects above 30 m² keeps the wet edge live without an emergency reorder.
Can I mix Bejca colours on the same facade for a multi-tone effect?
Blending two Bejca shades on the same panel produces layered, weathered grain — a teak first coat with a lighter birch top coat reads as sun-faded timber, which suits some heritage and coastal aesthetics. Trial the chosen combination on a stamped sample board first, since the cured-render shade affects how the two pigments interact.
Is Atlas Bejca Teak suitable for interior feature walls?
Atlas Bejca works on gypsum render, plasterboard, and interior mineral render, making it usable in reception areas, restaurant interiors, and residential feature walls. The low-VOC, water-based formula keeps the workspace comfortable during application and avoids the fire and moisture concerns associated with real timber cladding in interior settings.
How long does the teak colour hold on a UK exterior facade?
UV-stable pigments and the hydrophobic silicone-resin film maintain colour fidelity for around 5–12 years under typical UK weathering, depending on elevation exposure and orientation. Low-pressure water cleaning removes surface deposits and refreshes the finish, with no specialist re-staining cycle of the kind real timber requires.
What temperature range can I apply Atlas Bejca Teak in?
Application runs between +5 °C and +25 °C, with no rain forecast for 24 hours after the final coat. Working at the warmer end shortens the recoat interval and tightens the wet-edge window, so plan section sizes accordingly during UK summer afternoons. Outside this band, dispersion of the silicone-resin binder is compromised and full hydrophobic performance is not guaranteed.
Is Atlas Bejca Teak compatible with ETICS and ROKER EWI systems?
Atlas Bejca Teak is specified as the finish layer within ATLAS ETICS and ATLAS ROKER external wall insulation systems, both BBA-certified build-ups. Specifying the sealer alongside the certified render and adhesive components keeps the finished wood-effect facade inside the manufacturer-certified system rather than as an out-of-system aesthetic add-on.
